7-4 140 minutes] 7.8 [35 points] V 40 Vec +15 V R₁ Pel R₁ R2 H 8 8= -0% The transistors in the amplifier shown in Fig. 7.8.1 have ẞ=100, VBE = 0.7V, and negligible Early effect. (a) Design the circuit to obtain the following de [10 points] operating parameters: Vg1 +3 V, IE1 = 1 mA, VE2 +4 V, and Ig24mA. Use I=0.1 mA. Find the values of R1, R2, R3. (R4 + Rs), and R6- (b) Find the value of R4 (and hence Rs) that results [4 points] in Rin-10 k (c) Find R2- (d) Find the voltage gain et/y. (e) Find the voltage gain vo/t (0) Find the overall voltage gain/y. (g) Find the output resistance Rout [2 points] [3 points] [3 points] [1 point] [4 points] (h) In order to minimize nonlinear distortion, it is [8 points] required to keep the maximum signal across the base-emitter junction of each of Q1 and 2 to 5 mV. Under this constraint, what is the maximum peak-to-peak sine wave signal that can be obtained at the output? Figure 7.8.1
